Based on everything you posted, I'm going to say the place to start is the fact that the feed for those radiators comes off the side of the main. The radiator take offs should never come off the side of the main like they did, it allows the water to get in there, and possibly be picked up by the steam. They should always be at a 45 off the top, or even 90 from the top, the side is a strict no no. This will exacerbate the problems with the boiler piping possibly putting excess water into the main. And honestly, if they are going to make that change, might as well connect it in the proper location, but that's just me. Horizontal pipe, for me, just adds potential problems.

Sorry I didn't see that before, but after your drawing I can see it now. This may be a process of elimination, and this may just be the starting point.

Ok yea, that makes sense. I have asked my contractor, to ask his plumber to put this too a tee right to the main for over a month now. Now I am going to have to press him harder to do it. All of the other feeds are at 45 degrees. And all of the excess piping even if it is pitched correctly drives me a little crazy. Here is another photo to show the tee.

Probably easier to run a drip to the wet return as there's no room for a 45 takeoff. As long as the condensate has somewhere to go, not in the main, the horizontal takeoff can be 'made" to work.
